About this kit

5 mm common-cathode RGB LED, any colour. The RGB LED Brick is a carrier for the KY-016 module from common 37-in-1 sensor kits: plug the module into the socket and connect one cable to a TinkerPie SENSOR port. A small CH32V003 processor on the brick does the timing work, so your program simply reads the result over I2C.

Features

• 3 x 8-bit PWM channels
• Colour fades in the brick
• Status lights for robots
• Plug the kit module straight into the socket – no jumper wires
• One cable to any TinkerPie SENSOR port (I2C), BUS IN + BUS OUT to chain more bricks
• On-board CH32V003 does the timing – your code just reads the result

Specifications

How to use it with TinkerPie

1. Plug the KY-016 module into the 2.54 mm socket on the top edge. Match the pin names: the brick says R G B - (RGB) or - R G (two-colour), the module has the same letters.
2. Connect BUS IN to any TinkerPie SENSOR 1-4 port with a 4-pin JST-PH cable (the same cable as the other sensors).
3. More bricks? Plug the next one into BUS OUT. Two bricks of the same type need different addresses: bridge ADDR +1, +2 or +4 on the back (0x1C-0x1F; the first is 0x1C).
4. Install the TinkerPie and TinkerPieBricks Arduino libraries, open the quick-start sketch below, choose the board ESP32S3 Dev Module and upload.

Libraries: TinkerPie and TinkerPieBricks (Arduino IDE: Sketch → Include Library → Add .ZIP Library). Full guide: getting started with TinkerPie Bricks.

Quick start

Upload this, open the Serial Monitor at 115200 baud and watch the TinkerPie matrix.

// RGB LED Brick (TP-K10): quick start
// Reads the brick and shows the value on the TinkerPie matrix and in the Serial Monitor (115200 baud).
#include <TinkerPie.h>
#include <TinkerPieBricks.h>
using namespace tinkerpie;

tpb::KitLed rgb;

void setup() {
  Serial.begin(115200);
  tinkerpie::begin();            // also starts the SENSOR ports (I2C bus Wire1)
  if (!rgb.begin()) Serial.println("RGB LED Brick not found at 0x1C: check the cable to SENSOR 1-4");
  rgb.fade(300);
}

void loop() {
  rgb.color(255, 0, 0);   basic::pause(800);   // red
  rgb.color(0, 255, 0);   basic::pause(800);   // green
  rgb.color(0, 0, 255);   basic::pause(800);   // blue
  rgb.color(255, 0, 80);  basic::pause(800);   // pink
}

Project: Temperature colour lamp

The RGB LED shows the room temperature as a colour: blue when cold, green when comfortable, red when hot.
